To all whom it may concern:

Be it known that I, JOSEPH SAVANNAH IVALTON, a citizen of the United States, re-

siding at Burley,"in the county of Cassia and State of Idaho, have invented certain new and useful Improvements in Puncture Proof Automobile-Tires, of which thefollowing is a specification.

My invention relates to improvements in resilient tires for motor Vehicle wheels and is particularlydirected to providing a combined rubber and spring: metal tire, which will possess all of the advantages of a pneumatic tire without thedisadvantages thereof.

One of the objects of my invention is to provide a. tire of the above type, which includes a detachable tread member that may be renewed or replaced without discarding the whole tire.

rubber, which will withstand hard usage with very little wear. I

Another. object of my invention is to provide a resilient tire, which will be held in in its interior, a resilient buflier to limit the inward movement of -the tire tread.

A further object is to provide a tire which is of simple construction and inexpensivetomanufacture. p

With the foregoing objects outlined and with other objects in .view, which will appear as the description proceeds, my invention consists in the novel features hereinafter described in detail, illustrated in the accompanying'drawing and more particularly pointed out in the appended claims.

Referring to the drawing Figure 1 is a transverse vertical sectiona view of my improved tire.

Fig. 2 is a top plan view of a portion of V the flexible chain and showing the manner of connecting the same to the springs.

Fig. 3 is a vertical sectional view of the parts shown in Fig.2.

Fig. 4 is a of the spring p In the drawing 1y designates a rim, which as shown, is channel-shapedin cross section,

I11 my improved tire this detachable tread is formed of tough hard plan view of the feet of a few;

and which ,it will be in side ,view.

Thetire consists of a series of inverted U-shaped springs g bent to form channelshaped members gf and provided at their ends with feet 9 These springsare prefer- ,feet areflattened out. The springs are connected"to"t-he rim bymeans of screws 2', which pass between the feet'and engage a plate k that is located-on the interiorof the tire". A flexible chain 03 connects the channel-shaped portionof the springs and this connection is made by curling the edges of the chain links springs.

The springs and chain are embedded in vulcanized fiber f, whichcomblnes the parts 111 a unitary form, and an outer caslng 10 of hard rubber is secured to the fiber f in order to give a neat appearance tothe tire and to protect the fiber.

A resilient tire comprising a flexible easing inclosing Wire springs having chanshaped Wire springs having channel-shaped nel-shaped portions, a circumferential groove portions, a casing inciosing said springs and provided in the casing adjacent the channel having a circumferential groove adjacent the shaped portions of the springs, and'a reniovchannel-shaped portions of the springs, and 10 5 able tread located in said groove. a tread removably mounted in said groove. 2.
